Application filed February 19, 1919. Serial No. 278,065.

opening sometimes becomes clogged, and it has been customary for a long time to clear it with asmallpiece of wire about a thousandth of an inch smaller in diameter, which can be pushed through the opening. Various devices have been provided for con- .veniently having such piece of wire accessible, and providing it with a handle or means for applying it to the orifice, but the wire being very line it breaks off when it is held in such devices and they become useless.

The objects of this invention are to provide means for holding such piece of wire so that it can be used to clear the obstructed orifice of the nozzle, and yet can be carried in the pocket or tool bag or other convenient place when n ot in use; to obviate inadvertent breakage of the wire, as well as likelihood of it penetrating the clothing or person. of the carrier and causing damage or injury; to se cure a long handle which will resist downward pressure and at the same time fold up for convenience when not in use; to combine with said folding means for surrounding or inclosing the wire when not in use, to enable the wire to be detached from such holding means and a new one inserted, when desired; to obtain a simple and inexpensive construction, and to secure other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views,

Figure 1 is a perspective viewof my improved cleaner partially open;

F ig. 2 is a perspective view of the same closed,

Fig. 3 is a side view of the implement;

Fig. dis a cross-section of the same on line 44:, Fig. 3; i i

Fig. 5 is a longitudinal section on. line 5-5, Fig. 3, and

Fig. 6 is a detail )erspective. view of a certain guard for the sheath.

In the specific embodiment. of: the invention shown in said drawings, 1 indicatesv the piece of wire to be inserted in the orifice to clean the same, said wire being secured transversely at the endof a.l1older,2,'c0nsisting of astrip of sheet metal, by folding oneend ofthe sheet metal over the wire and clamping it down thereon, as at 3, it being understoodthat the wire lies transversely, of the holder Qand projects at one side sufficiently to allow insertion tothe proper extent, in the nozzle orifice.

This holder 2 is pivotally mounted at its end away from the wire 1 in a sheath 4., as by means of a bolt 5, said bolt being readily removable to allow the holder to be replaced by another if the wire becomes broken. It will be understood that a number of such holders, say half a dozen, are supplied with each of my improved sheaths, so that when the wire in one becomes broken it can be thrown away and another inserted.

The sheath 4 I have shown comprising a piece of sheet metal doubled upon a longitudinal central line so as to be U-shaped in cross-section, as shown in Fig. 4, and provide side walls 6, 6 sufiiciently spaced to receive the holder 2 between themselves. At the pivotal end of the device, the bolt 5 clamps the side walls 6, 6 and holder 2 close together, and yet not so tightly but that they can be swung with respect to each other. At its opposite end, the sheath provides a guard 7 whichis enlarged laterally of the sheath and also extended beyond the back or closed longitudinal edge of the sheath, so that when the holder closes into the sheath the wire 1 will lie in the guard and be surrounded or inclosed thereby. Thus the de vice, as shown in Fig. 3, can be carried in the pocket or tool bag without any danger of breaking off the fine wire 1, and yet said device is ready for instant use by opening the device as indicated in Fig. 1.

I have shown the guard formed by round ing the side walls 6, 6 of the sheath 0utwardly apart, as at 8, 8, and then bringing them together again at their end edges, the connecting back edge of the sheath being cut away. Then a sort of ferrule 9 is inserted between these bowed apart ends or the walls of the sheath, at the back edge of the sheath, and soldered thereto. I have shown the ferrule "9 as bent up out of sheet metal, the radial portions of which have been cut away, as at 10, to allow such bending, although it will be understood that it might be pressed out of sheet metal without such cutting away or might be formed in any other manner common in the art. Fur thermore, the said ferrule might be formed integral with the sheath, by a-little more complicated stamping process, and I do not wish to be understood as restricting myself to any of these details.

The open edge of the sheath is preferably provided with a recess 11 to provide access to a finger projection 12 at the upper edge of the holder 2, so that the said holder can be opened out of its sheath conveniently, and furthermore I have shown the holder with a recess 13 to receive the lower edge of the door opening in the casing of a conventional plumbers furnace and provide a clearance for the holder 2 to allow the insertion of the cleaning wire 1 into the orifices of the nozzle which is disposed slightly below the said door opening as will be understood by those skilled in the art.

Having thus described 7 the invention, what I claim is:

1. In a device of the character described, the combination of a holder formed of a flat strip of material, a wire projecting laterally from one edge thereof, a sheath for said holder, said sheath having a pair of spaced sides of a width substantially equal to the width of said holder to receive the holder between them, and a guard projecting from one edge of said sheath to receive the said wire on the holder when the holder is arranged between the sides of said sheath.

2. Ina device of the character described, the combination of a holder formed of a flat strip of material, a wire projecting laterally from one edge thereof, a sheath for said holder, said sheath having a pair of spaced sides of a width substantially equal to the width of said holder to receive the holder between them, and a tubular guard arranged. between the sides of said sheath and proj ecting from one edge thereof to receive the wire when the holder is arranged between the sides of said sheath. a
